The invention relates to a hand-held machine tool, in particular a hammer drill and/or chipping hammer. The tool according to the invention has a transmission device with a drive bearing that has at least one torque-transmitting means with a transmitting contour for transmitting a torque onto the drive bearing. According to the invention, the transmitting contour of the torque-transmitting means is produced by axial machining and/or a stamping and/or planning process.

Hand-held machine tool

The invention relates to a handheld machine tool, in particular a hammer drill and/or chipping hammer. The tool has an impacting unit which has at least one impacting pin and a guide unit which is provided for guiding the impacting pin. It is proposed that the guide unit is formed from at least two different materials.

Handheld power tool

The invention relates to a hand-held tool, in particular a rotary hammer, a percussion hammer, or a sabre saw. The hand-held tool is equipped with a drive unit and a stroke-generating element; the drive unit is embodied to move the stroke-generating element in a reciprocating fashion along a translation axis. The hand-held tool has at least one counterweight; the counterweight is operatively connected to the drive unit in such a way that it is possible to at least partially compensate for forces at least indirectly caused by the reciprocating motion. According to the invention, the counterweight in the hand-held tool is supported so that it is able to move, in particular to reciprocate, coaxial or parallel to the translation axis.

Hand-held tool with a counter-vibration device

A tool holder for a power tool, such as a drill hammer, a chisel hammer, and both, includes a striking mechanism for strikingly driving a tool, a base body, a drive part on which the base body is releasably mounted, at least one locking body for releasably mounting the base body on the drive part, a component having a throughgoing passage in which the at least one locking body is arranged, a securing body which radially fixes the at least one locking body in its engaging position, an actuating element for unlocking the securing body from its locking position to an unlocking position for radially reieasing the at least one locking body, and at least one holding element which holds the at least one locking body in the unlocking position of the securing body in the throughgoing passage. The holding element is lowered or lowerable into the component having the throughgoing passage and is overrun by the securing body.
